Hello IDL community,
I'm looking for a smart solution to find functions from my own lib
inside a self written function or procedure.
The idea is to get a tree of embedded self written functions.
My solution looks like this but I think there must be an easier way:
-generate a list of functions in user-lib
-Read the function where to search (openr)
-compare each line (string) with the list of lib functions
(how to extract function names egantly? -> strsplit with '=*(' :
definitely not)
-save coincide functions (strings) and go on searching into found
functions
Does anybody (I'm sure ;-) ) know how IDL find functions on compiling?
This may be exactly the right (fast) way...
Any ideas? ...Thanks for help...
Best regards
robert

That is: parse a file SOME_FILE.PRO and find if it contains any function
of your own library.

1- You need to load into memory (array) a list of your functions name.

2- Read each file line.

3- I think it will better with a STRMACTH or STREGEX.
This code can help you (extract from the old post
http://groups-beta.google.com/group/comp.lang.idl-pvwave/bro wse_thread/thread/bd3fc18ab72631ea/33089f602feb945c?hl=en#33 089f602feb945c):
Parse an entory file 'file' and found all functions or procedures that
starts with 'findstring'.
;PRO parse, file, findstring
;; Open the file test.lis:
OPENR, 1, file
;; Define a string variable:
line = ''
;; Loop until EOF is found:
found = 0
line_number = 0
WHILE (~ EOF(1)) AND (NOT found) DO BEGIN
;; Read a line of text:
READF, 1, line
;; Check if match your procedure/function name
match = STREGEX(STRUPCASE(line), '(PROCEDURE|FUNCTION) ' + $
''+STRUPCASE(findstring), $
/BOOLEAN)
IF match THEN print, line_number, '-', line
line_number++
ENDWHILE
;; Close the file:
CLOSE, 1
END

4- I dont understand this part. Save the function that coincides with
your function names and then find recursively into functions with
different name??

Thank you Benjamin, Reimar, Andrew and Antonio for your help, Antonios
example to use the "STREGEX" Function helped me to solve the problem
without compiling.
@ Mark: Maybe I have to excuse, that my english is not so good. With
"self written functions" i meant the functions belonging to my user
lib.
...but the previous authors understand my problem... so...?
